IMPORTANT NOTE: As of April 28, 2025, our Pointing Mortar ordering process will change to better match industry norms. We are moving away from our JS, JB, JL, etc. naming and adopting the industry standards: Type S, Type N, and Type O. See the guidelines below to determine which Type is best for your project.
Masonry | Type | Compressive Strength (PSI) |
Granite, Bluestone, Marble, Terra Cotta, Structural Brick, and Hard Stone | Type S | 1,800 - 2,500 |
Limestone, Sandstone, Brownstone, and Soft Stone | Type N | 750 - 1,200 |
Historic Brick | Type O | 350 - 750 |
Jahn M110 Pointing Mortars are single-component, cementitious, mineral based pointing mortars. We offer three (3) compressive strengths: Type S (1800 psi), Type N (750 psi), and Type O (350 psi)
Types M (2500 psi) is available as a special order; please send your request to info@cathedralstone.com.
